(Ceramic SubstrateByakozwe naWintrusetk)

LED ni ibikoresho bya semiconductor ya electroluminescent ihindura hafi 70% kugeza 80% byingufu zitangwa mubushyuhe. Niba ubu bushyuhe budashobora gukururwa neza binyuze muri substrate, kwiyongera kwubushyuhe bwihuriro bizavamo kugabanuka kwimikorere ya kwant imbere, kwangirika kwa fosifore, no kwihuta mubuzima bwigikoresho.

Imbaho gakondo zicapuwe zumuzunguruko (MCPCBs) zifite imbaraga nyinshi zo guhangana nubushyuhe bitewe nubushakashatsi bukenewe bwa polymer hagati yicyuma n’umuzunguruko, bigatuma barushaho kutabasha guhura n’ubushyuhe bukenerwa n’amashanyarazi menshi na ultra-power-LED. Ibinyuranye,ceramic substrateskomatanya insulasiyo hamwe nubushyuhe bwumuriro, ikuraho imiyoboro yubushyuhe bwimiterere kandi ihinduka inzira idashobora kwirindwa mubwihindurize.

1. Alumina (Al2O3)

Alumina ceramic kuri ubu ni ibintu byashizweho kandi bikoreshwa cyane muri substrate. Yerekana ubushyuhe buhoraho bwa 25-30 W / m.K, imbaraga zumukanishi, nibiranga dielectric nziza.

Ibyiza:

• Ikoranabuhanga rikuze

• Imbaraga zikomeye

• Kwirinda bihebuje

• Igiciro cyo gupiganwa cyane

Porogaramu: Byakoreshejwe cyane mumuri rusange, kumurika ibikoresho bya elegitoroniki, hamwe nuburyo bwo gupakira ibintu.

2. Nitride ya Aluminium (AlN)

Kumashanyarazi menshi ya COB hamwe namashanyarazi yo mu rwego rwa laser, AlN iragaragara cyane kubera ubushyuhe bwayo bukabije.

Ibyiza:

• Ubushyuhe bwumuriro bugera kuri 170-230 W / m.K, hafi inshuro umunani za alumina

• Coefficient yo kwagura ubushyuhe irahuza cyane nibikoresho bya semiconductor nka silicon na silicon karbide, bitezimbere cyane muburyo bwimikorere yibikoresho mubidukikije byamagare yumuriro.

Porogaramu: Amatara yimodoka, inganda zifite ingufu nyinshi, hamwe na UVC byimbitse ya ultraviolet.

3. Nitride ya Silicon (Si3N4)

Nitride ya Silicon ikemura ikibazo cya tekiniki yubukorikori bwa gakondo bwubutaka gakondo, bufite imbaraga zo kuvunika cyane nimbaraga zikomeye.

Ibyiza:

• Kurwanya ingaruka

• Kurwanya kunyeganyega

• Amashanyarazi meza

Porogaramu: Amatara yo mu rwego rwa gisirikare, ibikoresho byo mu kirere optoelectronic ibikoresho, hamwe na moderi yo mu rwego rwa LED bisaba kwizerwa cyane.
